NTSB narrative
THE ACFT EXPERIENCED A MAIN GEAR COLLAPSE DURING A LANDING ROLL. THE PLT CLAIMED THAT THE ACFT SUFFERED A FAILURE OF THEELECTRICAL SYSTEM SHORTLY AFTER INITIAL TAKEOFF. THE PLT LOWERED THE LNDG GEAR BUT WAS UNABLE TO ACHIEVE A GEAR DOWN & LOCKED INDICATION DUE TO THE ELECTRICAL FAILURE. THE RT MAIN GEAR COLLAPSED DURING LANDING. THIS WAS THE 1ST FLT SINCE AN ANNUAL INSPECTION DURING WHICH THE RT MAIN GEAR HYDRAULIC LINE WAS REPLACED. AFTER THE ACCIDENT, THE ACFT WAS JACKED UP ON THE RWY AND A BUNDLE OF SQUAT SWITCH WIRING FELL OUT OF THE WHEEL WELL. NO BUNDLE TIE WIRE WAS FOUND. AFTER THE ACFT WAS MOVED TO LANE AVIATION THE ENGINE WAS STARTED AND IT WAS DETERMINED THAT THE ALTERNATOR WAS NOT CHARGING. THE AMMETER INDICATED NO CHARGE OR DISCHARGE. WITH AN EXTERNAL JUMPER CABLE ATTACHED TO THE GEAR-UP RELAY A SUCCESSFUL GEAR RETRACTION WAS PERFORMED. AFTER THE BATTERY WAS CHARGED FROM AN EXTERNAL SOURCE, THE ALTERNATOR CAME ON LINE WITH 16.1 VOLTS BEFORE DROPPING OFF LINE AFTER APRX 2 MINS. THE ALTERNATOR PTS WERE PITTED & DIRTY. CLEANING DID NOT HELP.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
